Definition of atomic spectrum in English:

atomic spectrum

noun

The spectrum of frequencies of electromagnetic radiation emitted or absorbed during transitions of electrons between energy levels within an atom. Each element has a characteristic spectrum by which it can be recognized.
Example sentencesExamples
- Addition of this exclusion principle to the then current theory of atomic structure enabled many additional predictions to be made about atomic spectra and chemical combination.
- Each element has its own unique atomic spectrum.
- Although the Bohr model adequately explained how atomic spectra worked, there were several problems that bothered physicists and chemists.
- But then we wouldn't see the characteristic atomic spectra of the different elements - atoms would be able to produce light of any colour, which is not what we observe.
- He had been struggling to understand the details of atomic spectra.
- In 1913, Danish physicist Niels Bohr developed the first model of the atom that used the concepts of quantum theory to explain atomic spectra.
